11 Claims. ((31. 24255.3)

This invention relates to a dispenser for rolls of strip material and will be described as being embodied in a dispenser for toilet tissue provided in roll form, although it will be obvious to those skilled in the art that the principles of construction and mode of operation of the dispenser may be utilized with success in many other types of dispensers for strip material supplied in rolls.

One of the major problems encountered in public washrooms and lavatories is the maintenance of a continuous supply of toilet tissue and an associated problem is the prevention of waste by the public using the washrooms or lavatories. Many attempts have been made in the past to provide various types of dispensers for toilet tissue which incorporated means for providing an auxiliary or additional supply of toilet tissue after the exhaustion of the initial supply. However, none of the prior art devices has been quite acceptable and it is an object of the present invention to provide a toilet tissue dispenser foruse in the above mentioned environments which includes means for mounting a plurality of rolls of toilet tissue whereby one roll of tissue is exposed for use and whereby when said one roll of toilet tissue is exhausted an additional, supplementary roll can be exposed for use by the user of the device.

Another object of our invention is the provision of a toilet tissue dispenser which includes a mounting means adapted to facilitate the mounting of the dispenser on a suitable surface, said mounting means having a housing supported thereupon which is intended to enclose an auxiliary roll of toilet tissue, the roll of tissue in use being supported on the mounting means and being exposed for use until completely consumed. Therefore, the simultaneous use of a plurality of sources of tissue and the resultant Waste attributable to such availability are eliminated since the dispenser of our invention, of necessity, entails the complete consumption of the roll of tissue in use before the auxiliary roll can be exposed for use.

Another object of our invention is the provision of a toilet tissue dispenser of the aforementioned character wherein the housing of the dispenser is mounted for movement on an associated mounting means and wherein the housing is adapted to completely enclose and prevent the use of an auxiliary roll of tissue, the roll of toilet 'tissue in use being exposed to permit it to be utilized.

initially exposed roll of tissue has been exhausted and thus preventing the possible waste inherent in the presentation to the public of two sources of tissue.

Another object of our invention is the provision of a toilet tissue dispenser of the aforementioned character which includes retainer means adapted to prevent the atent Ofilice 2,98,450 Patented Oct. 13, 1959 removal of an exposed roll of tissue by a user thereof and thus eliminating the petty theft which results when conventional tissue dispensers are utilized.

Another object of our invention is the provision of a toilet tissue dispenser of the aforementioned character wherein the mount for the dispenser includes mounting means for supporting a plurality of toilet tissue rolls in operative relationship therewith and wherein the housing of the dispenser is retained in shielding relationship with one of the rolls of tissue to maintain it as an auxiliary supply until an exposed roll of tissue is completely consumed. An associated object of our invention is the provision of guide means on the mount for the housing whereby said housing can be moved with respect to its mount to expose the auxiliary roll of toilet tissue when the initial roll of tissue has been consumed.

An additional object of our invention is the provision of a toilet tissue dispenser of the aforementioned character which can be quickly and easily serviced by authorized personnel so that an exhaust roll may be readily replaced in the dispenser by an auxiliary roll which is housed within the housing until the roll in use has been exhausted.

Other objects and advantages of our invention will be apparent from the following specification and the accompanying drawings which are for the purpose of illustration only and in which:

Referring to the drawings and particularly to Figs. 1-4 thereof, we show a toilet tissue dispenser constructed in accordance with the'teachings of our invention and including a supporting bracket 12 which supports the dispenser 10 upon a wall 14, or other supporting surface. The supporting bracket 12, as best shown in Fig. 2 of the drawings, includes a cruciform wall engaging portion 16 provided with oppositely and laterally extending arms 18. Formed upon the outermost extremities of the arms 18 are roll retaining means 28, said roll retaining means being constituted by right-angilarly oriented, integrally formed tabs 22 which, as best shown in Figs. 1-4 of the drawings, serve to prevent outward longitudinal movement of the rolls of toilet tissue mounted in operative relationship with the dispenser 10 and thus prevent unauthorized removal of said rolls from operative relationship therewith.

The vertical leg 24 of the cruciform portion 16 of the bracket 12 is provided with an elliptical latch receiving opening 26 and has hingedly secured to its lower extremity a movable portion 28 of the supporting bracket 16, said movable portion including a rectangularly shaped plate 30 in the upper extremity of which is mounted a lock 32 having a bolt 34 receivable in the bolt receiving opening 26 in the upper extremity of the leg 24 or the cruciform portion 16 of the supporting bracket 12. The lower extremity of the rectangular plate 30 is hingedly secured to the lower extremity of the leg 24, as best illustrated in Fig. 2 of the drawings, whereby the plate 30 can be moved upwardly into a position in which it is juxtaposed to the vertically oriented leg 24 and in which the bolt 34 may engage the bolt receiving opening 26 in said leg whereby to maintain the plate 30 in operative relationship and in juxtaposition to the vertical leg 24, for purposes which will be described in greater detail below.

On the other hand, release of the bolt 34 from operative engagement with the opening 26 permits the plate 30 to be swung down into the position shown in Fig. 2 of the drawings.

Formed upon, or otherwise secured to, the rectangularly shaped plate 30 is a pair of outwardly projecting, laterally spaced mounting and guide plates 36 which, as will be described in greater detail below, serve as a sup port for a movable housing 40, said housing, as best illus* trated in Figs. 1-4, being movable from one extremity of the supporting bracket 12 to the other extremity thereof.

The housing 40 is formed from sheet metal, or the like, and includes a substantially semi-cylindrical enclosure portion 42, said enclosure portion being provided with lips 44 at the opposite extremities thereof and having its opposite edges fastened to a supporting frame 46; The supporting frame 46; is substantially rectangular in configuration and includes a pair of longitudinally oriented, vertically spaced angles 48, said angles being maintained in operative relationship with each other by vertically oriented connectors 50.

Formed in the upper and lower rear corners of each of the mounting and guide plates 36, as best shown in Fig. 6 of the drawings, is an angularly formed track means or guide notch 52, said notches receiving the elongated angles 48 constituting a part of the housing supporting name 46 and thus serving to guide and support the housing 40 during movement with respect to the mounting and guide plates 36 and the supporting bracket 12 incorporating said plates.

Fastened in and supported by the guide plates 36 is roll tissue mounting means 54 constituted by an elongated spindle 56 whose opposite extremities 58 extend beyond the opposite sides of the guide plates 36 and serve to support rolls of toilet tissue 60 and 62, respectively, in operative relationship with the dispenser 10, as best shown in Fig. 4 of the drawings.

Supported within the housing 40 and in operative relationship with the enclosure 42 thereof is a pair of toilet tissue roll blocking and locating means 64 and 66 which, as best shown in Figs. 4 through 8 of the drawings, are identical in construction and mode of operation. Because of the identity in construction and mode of operation of the blocking and locating means 64 and 66, the description of the locating means 64 will suffice as a description of the associated locating means 66.

Each of the blocking and locating means 64 and 66 is constituted by a sheet metal member 68 whose configuration is such that, as best shown in Figs. 5 and 6 of the drawings, the peripheral edge thereof conforms substantially to the interior surface of the enclosure portion 42 of the housing 40. It will be noted also that, as best shown in Fig. 8 of the drawings, the adjacent lip 44 on the enclosure portion 42 of the housing engages the peripheral edge of the blocking and locating member 68 to prevent outward movement of said blocking and locating member beyond the confines of the enclosure portion 42 of the housing 40.

The blocking and locating member 68 is, as best shown in Figs. 4-5 and 12 of the drawings, provided on its inner edge with a right-angularly oriented flange 70 and with a notch 72 for the reception of a guide and retainer track 74 which extends across and is secured to the supporting frame 46 of the housing 40.

Because of the securement and mounting of the blocking and locating members 68 constituting the blocking and locating means 64 to the housing 40 in the above described manner, limited movement between the housing 48 and the blocking and locating members 68 can take place without disturbing the physical connection of the blocking and locating members 68 to the housing 40, for a purpose which will be described in greater detail below.

The roll tissue blocking and locating member 68 is provided with a keyhole shaped opening 78 through which the roll mounting spindle 56 can pass and is also provided with latching and detent means indicated generally at 88, said latching and detent means including a U- shaped spring catch 82 mounted in a retainer 84 for vertical movement, said retainer having a centrally located opening 86 for the passage of the roll mounting spindle 56, as best shown in Fig. 12 of the drawings.

The spring catch 82 co-operates with detent notches 88 formed in the outer extremities of the guide and retainer track 74 to maintain the associated blocking and locating member 68 in operative relationship and predetermined position with the extremity of the guide and retainer track 74. Finger grips 90 are provided on the upper extremity of the arms of the U-shaped spring catch 82 to facilitate the release of the spring catch from the detent notches 88 in the guide and retainer track 74 and the co-operative relationship of the spring catch 82 with the guide and retainer track 74. More particularly, the detent notches 88 provided therein are graphically illustrated in Fig. 7 of the drawings, the full line portion of the figure illustrating the approach of the blocking and locating member 68 to the detent notches 88 on the track 74 and the dash line portion of the figure indicating the engagement of the spring catch 82 with the detent notches 88 to lock the member 68 against movement with respect to the track 74.

Each of the rolls 60 and 62 of toilet tissue is provided with a central core 92 formed from cardboard, plastic, or similar material, said core being cylindrical and of a size to fit over the opposite extremities 58 of the roll mounting spindle 56. Inserted in the inner extremity of each of the cores 92 is a trunnion or mounting member 94, said trunnion being formed from plastic or other suitable material and incorporating an elongated, cylindrical shank 96 which, as best illustrated in Fig. 11 of the drawings, has an enlarged cylindrical bearing portion 98 formed integrally therewith, said bearing portion terminating in a larger retainer portion 100 defining a shoulder 102 which, as best illustrated in Figs. 9' and of the drawings, is capable of engaging the lower portion of the keyhole shaped opening 78, as best illustrated in Fig. 9 of the drawings, to retain said trunnion or mounting member 94 in operative relationship with the blocking and locating member 68 in which it is inserted.-

When the dispenser 10 is in use, one of the rolls 62 of toilet tissue .is exposed for utilization while the other of the rolls 60 is, as best shown in Fig. 4 of the drawings, enclosed within the enclosure portion 42 of the housing 40. As graphically illustrated in Figs. 1 and 4 of the drawings, it is impossible for anyone other than authorized personnel to have access to the roll 60 which is located within the enclosure 42 of the housing and, as will be described hereinbelow, the exposed roll 62 must always be completely consumed before it will be possible for a person using the dispenser 10 to accomplish the movement of the enclosure portion 42 of the housing on the supporting bracket 12 in order to expose the auxiliary roll 60.

In order to service the dispenser 10 and to load it with rolls 60 and 62 of tissue, it is necessary to release the bolt 34 of the lock 32 by the utilization of a appropriate key. Release of the bolt 34 from the bolt receiving opening 26 in the rectangular plate 30, permits the housing 40 to be swung downwardly into the position shown in Fig. 2 of the drawings wherein the interior of the housing is exposed for the loading of rolls 60 and 62- of tissue therein. In order to load the rolls 60 and 62 of tissue in operative relationship with the dispenser 10, it is necessary to move the associated blocking and locating members 68 outwardly beyond the extremities 58 of the spindle 56 so that the retaining portion 100 of the trunnion can be inserted into the upper enlarged portion of the keyhole shaped opening 78 and then dropped downwardly into the smaller portion thereof so that the shoulder 102 upon the retaining portion 100 will engage the adjacent surface of the blocking and locating member 68 to hold the trunnion and thus the roll of toilet tissue in operative relationship therewith.

When the loading operation is accomplished at one side of the dispenser, the blocking and locating member 68 is shifted into a position adjacent an associated mounting and guide plate 36. The blocking and retaining member 68 on the other side of the dispenser 10 is then shifted outwardly beyond the associated extremity 58 of the spindle 56 and the loading operation repeated.

When the loading operation is completed, the housing 40 is shifted either to the left or the rightto expose the roll of tissue to be initially utilized and to enclose the roll of tissue which is to serve as an auxiliary roll. In the present instance, the initially utilized roll is the roll 62 and the auxiliary roll is the roll 60. When the loading operation is completed, the plate 30 is swung upwardly and locked against the vertical leg 24 of the cruciform portion 16 of the supporting bracket 12 and the housing is thus located between the roll retaining means 20 of the supporting bracket 12 so that neither the exposed roll 62 nor the enclosed roll 60 can be shifted longitudinally out of operative relationship with the associated extremity of the spindle 56.

It will be noted also that the retention of the trunnion 94- of each of the rolls 6t and 62 in associated keyhole shaped openings 78 in their associated blocking and locating members 68 prevents longitudinal shifting of the rolls upon associated extremities 58 of the spindle 56.

When the housing 40 is disposed in the left-hand position in overlying relationship with the auxiliary roll 60, the right-hand blocking and locating member 68 is locked against movement with respect to the-housing 40 by means of the engagement of the spring catch 82 with the detent notches 88 in the track 74. The position of the member 68 with respect to the housing 40 and, more V 6 particularly, with respect to the enclosure portion 42 of said housing is graphically illustrated in Fig. 4 of the drawings.

Therefore, should a user of the dispenser tend to move the enclosure portion 42 of the housing to the right in order to expose the auxiliary roll 60 before the exposed roll 62 has been completely used, such right-hand movemerit of the housing 40 will be resisted because of the fact that the housing 40 is latched to the blocking and locating member 68 and movement of the member 68 is itself prevented because of impingement of said member upon the unused, exposed roll 62 of toilet tissue. Therefore, the possibility that unauthorized persons may tamper with the dispenser 10 and expose the auxiliary roll prior to the complete exhaustion of the exposed roll is eliminated. In this manner, the wastage encountered in the use of conventional dual mounting of rolls of toilet tissue is eliminatedsince, as will be described immediately hereinbelow, the exposed roll must be completely exhausted before the auxiliary roll can be exposed to use.

When the exposed roll 62 of toilet tissue is completely exhausted, the diameter of the core which remains is less than the diameter of the opening 78 in the locking and locating member 68. Thus, the housing 48 may be shifted to the right to expose the auxiliary roll 68 of toilet tissue and this movement of the housing is accomplished merely by grasping the housing and causing the elongated angles 43 of the supporting frame 46 to traverse the guide and track notches 52 formed in the rear upper and lower corners of the mounting and guide plates 36 on the supporting bracket 12. When the housing 40 is thus moved, it assumes the position shown in Fig. 3 of the drawings and the auxiliary roll 68 of toilet tissue is now ready for utilization.

Once again the possibility that persons utilizing the dispenser 18 may tamper with the operation thereof occurs, since there might be a tendency to attempt to ascertain whether another roll is available within the housing 48 and movement of the housing 40 to cover the remaining exposed roll 60 might possibly result in a prankster or other person leaving the remaining roll covered within the housing so that a subsequent user would not realize that there was a supply of tissue available. However, such movement of the housing 40 into enclosing relationship with the exposed roll 60 is prevented since, when the housing 40 is shifted from the position shown in Fig. .1 of the drawings to the position shown in Fig. 3, the catch 82 engages the detent notches 88 on the track 74 since the track 74, being connected to the supporting frame 46 of the housing 48, is shifted simultaneously therewith. Thus, the blocking and locating member 68 is locked against the track 74 and the housing 40 cannot be moved since the exposed roll 60 of tissue prevents movement of the blocking member 68 and the connection of the blocking member 68 to the housing 40 prevents movement thereof.

In order to service the dispenser 10, the housing 40 is once again swung down into the position shown in Fig. 2 of the drawings and the intended auxiliary roll of tissue is mounted in operative relationship with the blocking member 68 for insertion of the trunnion 94 of said roll in operative relationship with the blocking member 68. The spring catch 82 is then released from engagement with the detent notches 88 and the roll pushed over the adjacent extremity 58 of the spindle 56 to cause the roll to be received within the interior of the housing 40.

It will be noted at this juncture that notches 104 are provided in the retaining means 20 to permit outward movement of the cores 92 of exhausted rolls past the retaining means 20 when the blocking and locating members 68 mounting the same are moved in juxtaposition to said retaining means.

After the dispenser 10 has been serviced in the above described manner, the housing 40 is swung back into 7 the original position and locked in the same by energization of the lock 32 and the housing will retain the position shown in Fig. 3 of the drawings until exhaustion of the roll of toilet tissue 60 takes place when the housing 40 can be shifted to the left to expose the waiting auxiliary roll.

It is readily apparent, therefore, that the toilet tissue dispenser of our invention can always maintain an auxiliary roll of tissue within the enclosure portion 42 of the housing 40 and that the auxiliary roll cannot be exposed for vandalism until complete exhaustion of the exposed roll takes place. Thus, wastage of the tissue is discouraged since only one roll is exposed at a time. Moreover, once an auxiliary roll has been exposed to view after the exhaustion of the initially exposed roll, it is not possible for tamperers to return the auxiliary roll to a position within the housing where it could not be perceived by persons desiring to use the same.

Because of the provision of the roll retaining means at the opposite extremities of the housing, it is impossible for a user to abstract the rolls of tissue from the housing and thus subject a subsequent user to an exhausted dispenser.

Also of considerable importance is the fact that the provision of the trunnions 94 in the cores 92 permits the rolls of tissue to be interlocked with the blocking and retaining members 68 with which they are associated, thus preventing sliding movement of the rolls on the associated extremities of the spindle 56. Moreover, the positive engagement of the'rolls of toilet tissue with the blocking and locating members 68 insures proper operation of the dispenser since the locating and blocking members 68 are always disposed in their proper operative relationship with respect to the housing 40.

An alternative embodiment 110 of the dispenser of our invention is shown in Figs. 13-19 of the drawings and since the only significant difference between the embodiment 110 and the dispenser previously disclosed hereinabove lies in the provision of a difierent type of a trunnion and a different type of latching and detent means, the other portions of the dispenser 110 which are identical with those of the dispenser 10 will be designated by identical reference numerals and no further description thereof appears to be indicated.

The blocking and retaining members 112 of the dispenser 110 are identical in configuration with the blocking and retaining members 68 of the dispenser 10 described hereinabove and incorporate right-angular flanges 70 and are provided with notches 72 for the reception of the guide and retainer track 74 which is mounted on the supporting frame 46 of the housing 40. Latching means 114 is mounted on the members 112, said latching means including a retainer plate 116 which mounts a spring catch 118, said spring catch being provided at its upper extremity with a finger grip 120.

Designed for co-operative relationship with the spring catch 118 is a trunnion 122 insertible in the end of an associated core 92, said trunnion including a mounting shank 124 receivable in the core and having a bearing portion 126 on which is provided a retainer portion 128, said retainer portion being provided with integral spreader lugs 130.

An opening 132 is formed in the blocking and retaining member 112 concentrically with a smaller opening 133 formed in the retainer plate 116. The lower portion of the spring catch 118 is engageable by cam surfaces 134 on the retainer plate 116 and has detent notches 136 on its lower extremity adapted to engage adjacent surfaces of the retainer plate 116 to maintain the spring catch 118 in a lowermost position in which it will engage the shoulder on the retainer portion 128' of the trunnion 122 to maintain an associated roll of toilet tissue in operative relationship with the blocking and locating member 112. r

Insertion of the trunnion 122 in operative relationship with the spring catch 118 is graphically illustrated in Figs. 17 and 18 of the drawings, Fig. 17 illustrating the initial location of the spreader lugs 130 between the opposed legs of the spring catch 118. When the lugs are located in the position shown in Fig. 17, they are rotated into the position shown in Fig. 18 wherein their opposite extremities engage the legs of the spring catch 118 and spread said legs to permit the rear retainer portion 128 of the trunnion 122 to move past the legs and to permit the shoulders defined by the retainer portion 128 of the trunnion 122 to be engaged by the spring catch 118. Thus, the trunnion 122 can be inserted in operative relation with the spring catch 118 when it is disposed in the lowermost, operative position shown in Fig. 15 of the drawings.

On the other hand, when the release of the trunnion 122 is desired, the finger grip 120 can be pulled upwardly to permit the legs of the catch 118 to spread and to permit the passage of the retaining or retainer portion 128 of the trunnion 122 therepast. In all other respects, the operation of the dispenser of our invention is identical with that of the previously disclosed dispenser 10 of our invention.

We thus provide by our invention a dispenser for various types of strip material in roll form which is characterizedby the provision of means whereby there is presented for use an initial exposed roll of material, while another auxiliary roll is maintained within a housing enclosure for instant availability upon complete consumption of the exposed roll. However, the enclosed roll is not available for tampering or mischievous vandalism and the housing is locked thereupon in enclosing relationshp therewith until complete consumption of the exposed roll takes place. Moreover, after the initially exposed roll has been consumed, the auxiliary roll can be readily exposed to view and to use by the simple expedient of laterally shifting the housing enclosing the auxiliary roll to expose the same.

Once the shifting of the housing has occurred, it is not possible to return the housing to the position of enclosing the auxiliary roll, thus preventing the possibility that a roll may be available for use but sealed within the housing without the knowledge of the person utilizing the dispenser.

The dispenser of our invention is also characterized by the ease with which is may be serviced and by its compact and attractive appearance.
